摘要： A wheel attachment to provide extra needed traction by a motor drawn vehicle when traveling on roadways covered with snow, ice or mud. It comprises a plurality of circularly spaced, flexible traction members overhanging the tread of a pair of wheels and control means operable from the driving position of the vehicle to selectively couple or uncouple the attachment relative to the wheels. The control means may comprise a driver's switch for operating an electromagnetically operated pin on the traction device cooperable with a hole in a disc rotatably mounted on a spindle at each wheel to selectively couple the device operatively to the hub at the respective wheel. Other alternative means are provided to control such coupling.
